Answer:

Eleanor's mean homework time is 4 hours. Eleanor's median homework time is 4 hours.

Explanation:

Step1: Calculate the mean

The mean formula is $\bar{x}=\frac{\sum_{i = 1}^{n}x_{i}}{n}$. Here, $x_1 = 3,x_2=4,x_3 = 5,x_4=4,x_5=5,x_6=4,x_7 = 3$, and $n = 7$. $\sum_{i=1}^{7}x_{i}=3 + 4+5+4+5+4+3=28$. Then $\bar{x}=\frac{28}{7}=4$.

Step2: Calculate the median

First, arrange the data in ascending - order: 3, 3, 4, 4, 4, 5, 5. Since $n = 7$ (an odd number), the median is the $\left(\frac{n + 1}{2}\right)$-th value. $\frac{7+1}{2}=4$-th value. The 4 - th value in the ordered data set is 4.
